The AQUALITY line of the Dr Irena Eris brand brings a new level of hydration thanks to a new-generation active ingredient – γ-polyglutamic acid (γ PGA), proven to be 5 times* more effective as a moisturizer than hyaluronic acid. This mesohybrid deep moisturizing system, developed at the Dr Irena Eris Centre for Science and Research, uses the innovative technology of biocompatible carriers that act as a magnet for H₂O molecules, which guarantees intensive, long-lasting hydration and anti-wrinkle action at all skin layers.

*In vitro test of water binding intensity and velocity.
